Question

我想使用扩展realm对象的类作为常规类，但是我的getFilter（）中有例外

ThrowingException 8，Realm从错误的线程访问。在/Users/cm/Realm/realm-java/realm/realm-library/src/main/cpp/io_realm_internal_OsResults.cpp第157行，。抛出了异常：从不正确的线程访问Realm。在/Users/cm/Realm/realm-java/realm/realm-library/src/main/cpp/io_realm_internal_OsResults.cpp第157行

这是我的适配器

List<ProductRealm> productsList, productsFiltered;
Context context;

public ProductAdapter(List<ProductRealm> productsList, Context context) {
    this.productsList = productsList;
    this.context = context;
}

@Override
public Filter getFilter() {
    Filter filter = new Filter() {
        @Override
        protected FilterResults performFiltering(CharSequence charSequence) {
            String charString = charSequence.toString();
            if (charString.isEmpty()) {
                productsFiltered = productsList;
            } else {
                List<ProductRealm> filteredList = new ArrayList<>();
                for (ProductRealm row : productsList) {
                    if (row.getName().toLowerCase().contains(charString.toLowerCase())) {
                        filteredList.add(row);
                    }
                }

                productsFiltered = filteredList;
            }

            FilterResults filterResults = new FilterResults();
            filterResults.values = productsFiltered;
            return filterResults;
        }

        @Override
        protected void publishResults(CharSequence charSequence, FilterResults filterResults) {
            notifyDataSetChanged();
        }
    };

    return filter;
}

这是我的片段

viewModel.productsList.observe(this, new Observer<List<ProductRealm>>() {
        @Override
        public void onChanged(@Nullable List<ProductRealm> productRealms) {
            productAdapter = new ProductAdapter(viewModel.productsList.getValue(), getContext());
            rvProduct.setAdapter(productAdapter);
        }
    });

查看模型

public MutableLiveData<List<ProductRealm>> productsList = new MutableLiveData<>();

RealmResults<ProductRealm> results = realm.where(ProductRealm.class).findAll();
productsList.setValue(results);

将对象更改为unmanaged域对象后，可以使用将RealmObject扩展为常规对象的类。

这可以使用文档中描述的方法copyFromRealm来实现 https://realm.io/docs/java/latest/api/io/realm/Realm.html#copyFromRealm-E-

我可以使用扩展RealmObject作为常规对象的类吗？
